Voice Cloning
Clone a voice from a short sample.
Upload a clear recording of a voice you have the right to use, give it a name, and use it for text to speech whenever you like. Your recording is never uploaded.
In short: AI voice cloning learns a voice from a short, clear recording (about 10 to 30 seconds) and lets you type any text in that voice. KUKU Labs does it in your browser, only for voices you own or have permission to use. A free account can clone a voice and speak with it within its 5,000 characters a week; Basic ($10 a month) makes it unlimited.
How it works
- 1
Add a short, clear recording
A single speaker, little background noise. KUKU Labs picks the clearest stretch of your file automatically.
- 2
Confirm you have permission
Only clone your own voice, or one you have clear permission to use. You confirm this each time.
- 3
Use it
Your cloned voice is saved in your browser and appears in its own section, above your other voices, ready for any text.
What you get
Works from a short sample
You don’t need a studio recording: a clean ten seconds of speech is enough to start.
Private and reusable
Only the voice’s “fingerprint” is kept, in your own browser, linked to your account. Your original recording is not uploaded or kept.
Per-language voices
A cloned voice belongs to the language you made it in.
Consent built in
Every clone starts with a clear confirmation that you have the right to use that voice.
Clean it up first
Use the free Voice Enhancer to remove noise from a sample before you clone it.
What AI voice cloning is
Voice cloning studies a short recording of a voice and builds a reusable digital version of it. You can then type any text and hear it spoken in that voice. It is useful for your own voiceovers when you do not want to record every line again, and for projects where you have the speaker’s permission.
What you need
- A clear recording of one speaker, ideally 10 to 30 seconds, in a quiet room with no music behind it
- The right to use that voice: it is your own, or the speaker has clearly agreed
- A KUKU Labs account (free accounts can clone too, within their 5,000 characters a week)
How good will it sound?
The clone can only be as good as the recording it learns from. A clean, steady recording gives the best result; background noise, echo and music are copied too. If your recording is noisy, clean it first with the free Voice Enhancer. Cloning usually takes more time than using a built-in voice, so if you want a quick result, use one of the 102 built-in voices.
A cloned voice belongs to the language you made it in. Cloning supports English, German, Italian, Portuguese and Spanish.
What you can use a clone for
- Narrating your videos in your own voice without recording every line again
- Keeping one consistent voice across a whole series of videos, lessons or episodes
- Fixing a sentence or adding a line later without setting up the microphone again
- Giving a character, a brand or a project its own voice, when you have the speaker’s permission
Consent and safety
Only clone your own voice, or a voice you have clear, informed permission to use. You confirm this every time you clone, and you must never use a cloned voice to mislead people into thinking a real person said something they did not. Our Terms explain the rules. For a walk-through, read how to clone a voice.
Your recording stays with you.
Your recording is processed in your browser and isn’t uploaded to our servers, and the saved voice lives in your own browser.
Questions
How long should the sample be?
A clear recording of a single speaker, ideally 10–30 seconds. KUKU Labs automatically selects the clearest stretch, so a longer clean recording is fine.
Can I clone someone else’s voice?
Only with their clear permission. You must confirm that you have it before cloning, and you must not use a cloned voice to mislead people or to commit fraud. Our Terms explain the rules.
Is my recording stored?
No. It is processed in your browser, and only the saved voice (a set of numbers, not audio) stays in your browser.
Do I need a plan?
No. A free account can clone a voice and speak with it, within its 5,000 characters a week. The Basic plan ($10 a month, or $100 a year, renewing until you cancel) makes it unlimited.
Why does cloning take longer than the built-in voices?
Cloning has more to do: it studies your recording, builds the voice, and then speaks with it, which takes more time than using a built-in voice. If you want a quick result, use one of the 102 built-in voices in Text to Speech.
What if I clear my browser data?
Saved voices live in your browser, so clearing site data removes them. You can clone the voice again from a sample.
